Amateur flaming-arrow archers (not a phrase that inspires confidence!) kept the fires burning in Alberta's gas towers in 1960:
Waste gas fumes burning off from this flare tower at Nevis. Alberta, sometimes blow out, and the mechanical relighting device doesn't always work. The oilmen keep a bow and a fire arrow handy and relight the flare by shooting a flame through the fumes. It doesn't require any skill at archery–note this oiler's unusual form.
